doesn't `Runtime.addShutdownHook` have a synchronisation point. like all writes need to have occurred before `ApplicationShutdownHooks.add` has been called so there is no publish problem. https://github.com/openjdk/jdk/blob/2fa09333ef0ac2dc1e44292f8d45d4571cb22cca/src/java.base/share/classes/java/lang/Runtime.java#L69 https://github.com/openjdk/jdk/blob/2fa09333ef0ac2dc1e44292f8d45d4571cb22cca/src/java.base/share/classes/java/lang/ApplicationShutdownHooks.java#L65 maybe I'm missing something that is java specific with the way constructors work. I'm guessing even without the synchronisation point java lets you share objects in a way that would normally be considered unsafe as long as all the fields are final.
